Employee profile pictures: PATCH/POST and/or last modified in GET request

Hi guys, I'm looking to integrate our employee profile pictures across our systems here and running into a few limitations with the Personio API, so a few questions:

Is there any plan to add POST/PATCH for profile pictures to enable us to add/update via the API?
Is there any plan to add a last modified date to the profile picture object that gets returned in a GET call to the employees endpoint?

Currently, I'm not able to filter out only employee photos that have been updated in a given timeframe (to then sync to our other systems), so would have to rely on the 'last_modified_at' object, which captures any change to employee profile data.

Any info would be great.
